It takes 8 hours to clean 12 houses so that’s 8/12 to find how many hours it take to clean one house, 8/12 is equal 2/3 . So it takes 2/3 of an hour to clean one house. 2/3 times 12 equals 8. So you want to find how many houses you can clean in 12 hours. The equation is 12= 2/3x , x=18. The answer is 18 houses. Check the work cus I sure didn’t lol, hope this helps
I’m pretty sure it’s number two in my opinion
Given:
To find out:
Volume of cube =?
Formula used:
volume of cube =(edge)³
Solution:
volume of cube =(9)³=>729m³
Answer:
The height is 5ft
Step-by-step explanation:
We know the area is 30ft^2 and the base is 12 ft.
Plug that information in the formula for the area of a triangle,
Formula for area of a triangle:
A = (1/2)bh (area is one half of the product of the base and height)
The question gives us A = 30, and b = 12. We can plug them in and find h
30 = (1/2)(12)h
Now solve for h
30 = 6h (1/2)(12) means '12 times one half' or 'half of 12' which is 6
5 = h (30 divided by 6 is equal to 5)
(x1,y1) = (-2,7)
m = -5
(x,y) = (a,2)
Forming the equation,
(y-y1) = m(x-x1)
y - 7 = -5[x - (-2)]
y - 7 = -5x - 10
y + 5x = -3
Putting the values of (x,y) we get,
2 + 5a = -3
5a = -5
a = -1
